Steps to reproduce the error >>> import math >>> 1/math.log(math.pow(30,0.5),2) == 2/math.log(30,2) True >>> 1/math.log(math.pow(9,0.5),2) == 2/math.log(9,2) True >>> 1/math.log(math.pow(15,0.5),2) == 2/math.log(15,2) True >>> 1/math.log(math.pow(8,0.5),2) == 2/math.log(8,2) False >>> 2/math.log(8,2) 0.6666666666666666 >>> 1/math.log(math.pow(8,0.5),2) 0.6666666666666665 I reproduced the error in Python : Python 3.5.3 and Python 2.7.13 ---------- components: Library (Lib) messages: 336132 nosy: Marcelo Marotta priority: normal severity: normal status: open title: Division using math.pow and math.log approximation fails type: behavior _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue36055> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
